The company is now recalling 907,000 cars, mostly Corollas, due to air bags that can improperly inflate when the vehicle’s electronic signals damage a chip in the part that controls the air bags. It also is recalling 385,000 Lexus IS luxury cars with wipers that can get stuck in heavy snow.

Initially, the Japanese automaker had said there were no accidents related to either problem, but a Toyota Motor Corp. spokesman said Wednesday two crashes were reported in the United States related to the air bag.

As part of the air bag recall, Toyota is recalling some 752,000 Corolla and Corolla Matrix cars in the United States, about 141,000 vehicles in Canada, and thousands in Japan and Mexico that were made between December 2001 and May 2004.

The problem wipers affect three kinds of Lexus IS models, made from May 2005 to October 2011, including 270,000 vehicles in the United States.

The recall also affects the Lexus IS sold in Canada, Europe, the Middle East, and China, Toyota said.
